Except output voltage ratings, these smart high-side driver equivalent. UCN5890A/LW rated operation with load supply voltages minimum output sustaining voltage UCN5891A/LW optimized operation with supply voltages sustaining). BiMOS devices have higher data-input rates than original BiMOS circuits. With supply, they will operate least MHz. higher speeds possible. CMOS inputs compatible with standard CMOS NMOS logic levels. circuits require appropriate pull-up resistors ensure proper input-logic high. CMOS serial data output, allows cascading these devices multiple drive-line applications required many matrix, alphanumeric, graph displays. Suffix devices supplied standard dual in-line plastic package with copper lead frame enhanced package power dissipation characteristics. Suffix `LW' devices supplied standard wide-body SOIC package surface-mount applications. Similar driver, featuring reduced output saturation voltage, UCN5895A A5895SLW. Complementary, 8-bit serial-input, latched sink drivers Series UCN5820A.

Information present register transferred respective latch when STROBE high (serial-to-parallel conversion). latches will continue accept data long STROBE held high. Applications where latches bypassed (STROBE tied high) will require that OUTPUT ENABLE input high during serial data entry. When OUTPUT ENABLE input high, output buffers disabled (off) without affecting information stored latches shift register. With OUTPUT ENABLE input low, outputs controlled state their respective latches.
